BARREL-DRAINER.

SPECIFICATION forming part of Letters Patent No. 551,829, dated December 24, 1895.

Application filed March 2 5, 1 8 9 5.

Beit known that I, CHARLES A. MITCHELL, a citizen of the United States, residing in the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Barrel-Drainers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to devices technically known as barrel-drainers, and has for its object to provide an apparatus of that character which shall be adapted to be readily applied to or removed from a barrel at the bunghole thereof and form a tight connection therewith, and therebypermit the barrel to be thoroughly and completely drained of its contents.

To that end my invention consists in con structing the device in the manner hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a barrel, with the drainer applied thereto, and a discharge. Fig. 21s a vertical sectional view of the drainer on the line w :20 of Fig. 1. Fig. 3 is a like View on the line y y of Fig. 2. Fig. 4 is a plan view of the closing-plate at the base of the device, and Fig. 5 a view of its two parts or sections.

As is well known, itis difficult to thoroughly drain or empty the contents of barrels containing semi-liquids, such as molasses, &c., otherwise than at the bung-hole at the center of the barrel, and to do this requires the barrel to be placed upon its side. Hence devices have been made to connect the draintube with the barrel at the bung-hole. Such devices must necessarily be capable of ready application to and removalfrom the barrel and form a tight joint therewith. My invention accomplishes these objects perfectly.

In Fig. 1 the barrel is indicated at A as supported upon its side, and the drainer B is applied to the bung-hole thereof, as shown, the drain-pipe 0 being screwed into the threaded end of the drainer, the drawing showing this pipe extending longitudinally of the barrel for the purpose of illustration only, the pipe being applied transversely of the barrel in usual practice.

The drainer B is shown in two sectional views on diameters in Figs. 2 and 3. By way Ctr:

Serial No. 543,015. (No model.)

of showing the application thereof to the barrel a section'of the barrel is indicated at D in both figures, d representing the bung-hole. The casing E is in the form of a hollow elbow, the outlet end (marked B) being screwthreaded, preferably on the interior, to con nect therewith the drain-pipe O. This casing is preferably cast with an annular flange E at its inlet end, which is recessed annularly on its top surface to contain and hold within such recess a rubber or other gasket Eiwhich, when the drainer is applied to the barrel, forms a tight joint therewith around the bunghole. The base of the casing E is perforated to admit the passage ofthe screw-threaded actuating-rod F, which is reciprocated by means of a threaded thimble F, supplied with operating-arms F Between the thimble F and the base of the casing E is placed a gasket or packing N, which rests in an annular recess in the casing E around the opening therein provided for the screw-rod F, as before mentioned. A washer H, made in two sections and shown in Figs. 4 and 5, is provided to maintain the thimble F and washer N in place. An annular rim n is cast upon the thimble and rests in an annular recess n on the inner face'of the washer. The latter is screwed to the casing by screws h, as indicated in Fig. 3. The sections of the washer H are shown in Fig. 5, the meeting edges of the sections overlapping each other, for which purpose the section H is recessed, as indicated at 71 and the sections H having extended thin ends (indicated at 72 and adapted to fit the opposite recesses h2 in the section H.

Mounted upon the upper end of the screwrod F, within the casing E, is a cross-bar S,

at each end of which is hinged a finger T order that it may have a greater inward latcross-bar S, and a frame K is secured by its angle or flange ends to the base of the casing E (see Fig. 3) crosswise between the vertical ends of the spring M and the cross-bar S, and thus operates as a guide for said cross-bar as it is raised and lowered by the screw-rod F. Incidentally the edge sides of this frame K limit the inward throw of the springs and of the fingers.

The operation of the device is as follows: The drawings show the screw-rod F and its connected parts at the limit of its downward movement, and the barrel-drainer is thus fast upon the barrel. The ends of the fingers T are within the bung-hole, and the lips t thereof bear against the inner surface of the barrel side around the bung-hole. A sufficient downward movement of the screw-rod forces these lips 15 tightly against the inner surface of the barrel side, and by the same movement forces the top annular edge E of the casing E with its contained gasket E against the outer surface of the barrel side, and thus a perfectlytight joint is formed therewith.

To release the device from the barrel, the screw-rod F is given a reverse or upward movement, which causes the fingers to contact with the cam projections G in the interior of the casing E, and thus the fingers are thrown inward and toward each other, the lips or projection 23 thereof being thus released from hold upon the barrel.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A barrel draining device consisting essentially of the following parts in combination, a hollow casing having suitably arranged inlet and outlet openings and interior cam projections G, means to form a tight joint between the inlet opening and the surface of the barrel to which the device is applied, an actuating rod extending through the base of the casing, a cross bar mounted on said rod within the casing, a pair of clutchin g fingers pivotally mounted on opposite ends of the cross-bar and adapted when moved vertically to contactwith the cam projections on the interior of the casing, and an outwardly bearing spring adapted to keep the clutching fingers normally apart; substantially as described.

2. In a device of the character described consisting of the combination with the elbow shaped hollow casing E, having interior cam projections G, and suitably arranged inlet and outlet openings, of a cross-bar S maintained within the casing, a pair of clutching fingers T pivotally mounted thereon, and provided with swells t, outwardly bearing springs M and a guiding frame K mounted on the cross bar between the clutching fingers, an actuating rod F, means to reciprocate the rod outside the casing; and means to make atight joint around the aperture in the base of the casing through which the actuating rod is operated; substantially as described.

3. In a device of the character described, the casing E, having an annular gasket 011 its inlet opening, a screw threaded outlet R, interior cam projections G, a basal opening with annular recess and a packing N therein, in combination with a threaded thimblc I having an annular flange n, a washer 11 constructed in two sections recessed at n and having overlapping meeting edges 7L2 h an actuating screw rod F, a cross-barS mounted on the end of the rod within the casing E, a pair of clutching fingers T hinged to the crossbar, and an o utwardly bearing spring adapted to maintain the clutching fingers normally apart; substantially as described.

In testimony whereof I have hereunto affixed my signature this 21st day of March, A. D. 1895.

CHARLES A. MITCHELL.
